' 'llie drawings show, and the following de scription sets forth, a machine of the self- -feeding blank, rotary convolute-winding and lshell stripping type as having my improvements applied thereto and coordinated with the operative mechanisms thereof, but I do not limit myself to the use of my improved shell closing or end folding means in connection with the irachine shown an described, nor even with a machine of that general type, as l am well aware that my inte provements may be applied to other may chines of this general type and even to machines v'hich do not actually Wind oi form the tube or shell from a blank. My shell or .tube end closing or folding mechanism constituting'the present invention maybe usedv in connection with any' means for support-l ing a 'tube or shell by a mandrel in such manner that the open end of'said tube or shell can be folded or closed by my improvements, and it is possible to employ my invention in connection with a mandrel from which the tube could be slipped or 'stripped by hand operation after the end had been closed or 'folded by my invention.
